CLYDE S. MORSE, OF DE KALB, ILLINOIS.

AUTOMATIC SASH LOCK AND HOLDER.

Patented June 13, 1916.

Application filed January 5, 1916. Serial N 0. 70,374.

Specification of Letters Patent.

T0 oZZa Jwmz't may concern of the holder or look. Fig. 6 is a side view Be it known that I, CLYDE S. Monsn, a citizen of the United States, and resident of De Kalb, in the county of Dekalb and State.

of Illinois, have invented certain new and useful Improvements in Automatic Sash Locks and Holders, of which the following is a specification.

This invention relates to improvements in a sash-lock, holder or fastener, of a type in which the sash-frame, with which it is designed to cooperate, will be automatically locked or fastened thereby, in a safe, firm and secure manner against vertical movement, and it consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal objects of the invention, are, to provide a sash-lock or holder which shall be extremely simple in its construction, automatic in its looking or fastening operation, inexpensive to manufacture, easily applied to a window-casing, almost invisible when in use, and inaccessible toburglars, or from the outside of the window.

Another object is to so construct and arrange the parts of the device that it willcooperate with the window sash in such a manner that the ordinary sash-weights may be dispensed with, if desired, yet so that the sash may be easily raised or lowered and firmly held in any position at which it may be stopped, and so that it will not rattle.

ther objects and advantages of the in vention will be disclosed in the subjoined, description and explanation.

In the accompanying drawing, which serves to illustrate the invention, Figure 1 is a face view of the lock or holder detached from the window casing and illustratin by continuous lines, the positions the loc ring levers will occupy when the window-sash is locked thereby, and by dotted lines, the positions to which they may be moved to release the window sash. Fig. 2 is a side View of the holder. Fig. 3 is a view partly in section and partly in elevation, showing the upper part of the holding plate illustrated in Figs. 1 and 2 removed. Fig. 4: is a perspective view of the blankout of which the holding plate is made, illustrating by dotted lines the position to which a part thereof may be turned. Fig. 5 is a front face view showing a modification in the construction thereof. Fig 7 is a View in elevation of a portion of one of the jambs or sides of a window frame showing the lock or holder mounted thereon, and Fig. 8 is a side view of like parts.

Like numerals of reference refer to corresponding parts throughout the different views of the drawing.

Referring now to Figs. 1 to 4 inclusive of the drawing, the reference numeral 10 designates the holding or securing plate of the lock, which plate is substantially rectangular in shape as shown, and is provided near one of its edges with openings 11 for the passage of screws used to secure the plate 10 to the window jamb or side of the window frame and within the groove 12 in which the sash 13 operates.

In order that the lock may always be in position to engage and control the move ments of the sash, I locate the lock or holder within the groove or channel of the jamb or side of the window frame at a point near the top rail of the lower sash and the bottom rail of the upper sash, when they are in their normal positions, and in order that the holding plate 10 may not interfere with the movement of the sash 13 said plate is countersunk or set in a mortise let in the side of the window frame as will be readily understood by reference to Fig. 7 of the drawing. The plate 10 is also provided with openings 15 in which the outer ends 16 of the locking levers 17 are located for pivotal movement. Each of the levers 17 has on its free end an arm 18 which is eX- tended at a right angle or substantially so to its lever 17 as is clearly shown in Figs. 2 and 6 of the drawing. The plate 10 is pro vided, as shown in Figs. 1 and f with a flap 19which is bent over the pivoted por tions of the levers 17 and downwardly between the same as at 19 in Fig. l of the drawing. The levers 17 and their arms 18 may be made of any suitable size, form and and material, but by preference of metal and substantially of the shape shown in Figs. 2 and 3, so that they will be interchangeable, or rather that either one of the levers can be located in either of the openings 15 of the securing plate. The flap or overlying portion 19 may be of such rigidity as to require no rivets to hold it in its overlying position, or it may be riveted in position shown in Figs. 5 and 6 of the draw,
